The Edelbrock & Roush TVS supercharges don't run a flat psi number. "5 psi" is more like "5 psi that ramps to 7 psi". Somebody with a Roush TVS actually saw their 5 psi ramp to 9 psi.
John's car has a 3.875" stock size "5psi" pulley installed. The same one that comes on the E force supercharger in their kit. The car see around 5-6 psi at the hit of the throttle and as the RPM band goes up so does the boost output. At the end of the run John sees a peak of over 7 psi boost.
The difference in us making 434 RWHP and the 424 we reported in the first tune was just some small adjustments. The car is still tuned in a very, very conservative manor. Im sure John will have noticed improved throttle response and better driveability with the tune as well.
Congrats man!! As you are now slightly higher than mine I wonder what tweaks they did to get you that additional peak TQ... but both are proportionately higher (about 10).
With the stock pump, how close are you to being max'd out??

I know it had to do with the timing, throttle response, and maybe something else. Jim could clarify hopefully.
Stock pump...LOL - I am at my max, or very close. I may go with the upgrade kit later on this year, but we will see how much money I have. That was with a factor of 1.05 (around 100 F in the dyno room), so in reality it should be close to 450 (+/- some).
So my 2015 Mustang SC was completed yesterday and Dyno'd with the Edelbrock tune. These are my results.... I gained around 100HP? Edelbrock advertises 200 HP...Should I be disappointed?
